About Refractal


A sourcing agent misclassified one of us by 3,300 miles. Today, we are building the runtime trust layer to stop agents making these mistakes at industrial scale.

Backed by

Adam was an investor at Creator Fund, backing early-stage Applied AI and cyber founders across Europe. Alongside the day job he was building his own LLM agents for sourcing founders and scaling his own work. He spent more time patching the agents’ mistakes than using their output.

Strajo was on the other side of the Atlantic. After coming from Montenegro to study Offensive Cyber at the US Naval Academy, he joined MIT to research Adversarial Intelligence. He spent time in research across Microsoft, NASA, NSA, and Vectra, where he wrote a paper using Claude for adversarial red-teaming.

Adam’s sourcing agent detected Strajo’s paper and flagged him as a potential founder, in Cambridge, UK. Except he was in Cambridge, Massachusetts.

Adam only spotted the mistake when manually reviewing the Excel output. We started Refractal to stop these subtle failures that happen today on an industrial scale.

Where Strajo actually was. 3,314 miles off. No policy check stopped it.
